UNSPSC 32131022: Ceramic for printed circuit board PCB substrates

Various ceramic materials used in the manufacture of Printed Circuit Board substrates.

UNSPSC 32131022 Ceramic for printed circuit board PCB substrates (Commodity) does not align with the state and local contract opportunities currently tagged to this code. The recent solicitations in the dataset—custom printed circuit boards for research applications, law enforcement equipment, school security systems, electrical parts and supplies, water treatment equipment, and printing services—span manufacturing, security, facilities management, and administrative services rather than ceramic substrates specifically. The code shows minimal relevant recent activity at the state and local level, with only the University of Wisconsin-Madison's APxF Rev K3 Custom Printed Circuit Boards RFB (due July 20, 2026) bearing any direct connection to PCB procurement. The mismatch between the code's nominal scope and the work being solicited suggests either misclassification of opportunities in the source data or a narrow niche for this commodity within state and local procurement.

Activity under this code is concentrated in Wisconsin and dispersed across California, Florida, and Arizona, but the geographic pattern reflects opportunities tagged broadly to electronics and components rather than ceramic substrates as a specific input material. The University of Wisconsin-Madison remains the only issuing body soliciting PCB-related work in the recent dataset, with inquiries directed to Eric Thompson at eric.thompson@wisc.edu. Without additional opportunities demonstrating sustained state and local demand for ceramic PCB substrates as a procurement category, the code appears to carry limited near-term business development signal for suppliers targeting municipal, county, or school district contracts.
